DETAILED DESCRIPTION

Some embodiments of the present disclosure will now be described morefully hereinafter with reference to the accompanying drawings, in whichsome, but not all embodiments of the disclosure are shown. Indeed, thesedisclosures may be embodied in many different forms and should not beconstrued as limited to the embodiments set forth herein; rather, theseembodiments are provided so that this disclosure will satisfy applicablelegal requirements. Like numbers refer to like elements throughout.Terminology used in this patent is not meant to be limiting insofar asdevices described herein, or portions thereof, may be attached orutilized in other orientations

The term “comprising” means “including but not limited to,” and shouldbe interpreted in the manner it is typically used in the patent context.Use of broader terms such as comprises, includes, and having should beunderstood to provide support for narrower terms such as consisting of,consisting essentially of, and comprised substantially of

The phrases “in one embodiment,” “according to one embodiment,” and thelike generally mean that the particular feature, structure, orcharacteristic following the phrase may be included in at least oneembodiment of the present disclosure, and may be included in more thanone embodiment of the present disclosure (importantly, such phrases donot necessarily refer to the same embodiment)

The word “exemplary” is used herein to mean “serving as an example,instance, or illustration.” Any implementation described herein as“exemplary” is not necessarily to be construed as preferred oradvantageous over other implementations.

If the specification states a component or feature “may,” “can,”“could,” “should,” “would,” “preferably,” “possibly,” “typically,”“optionally,” “for example,” “often,” or “might” (or other suchlanguage) be included or have a characteristic, that particularcomponent or feature is not required to be included or to have thecharacteristic. Such component or feature may be optionally included insome embodiments, or it may be excluded.

In work environments, such as warehouses, retails stores, materialhandling environments and/or the like, a worker may have to move aroundthe facility to perform various operations such as, but not limited to,carrying objects, picking objects from racks, scanning the objects,dimensioning the objects, and/or the like. Typically, the worker mayutilize electronic devices such as hand-held scanners, barcode readers,smartphones, etc. to perform the aforementioned operations. A typicalelectronic device may include a display screen that may be configured todisplay tasks for the worker to perform. The worker may further provideinputs through the display screens to update the status of the tasks.For instance, the worker may provide touch input through the displayscreen to mark a task as completed.

Certain work environments maintain sub-zero temperatures. Operatingelectronic devices in such work environments may be a challenge due toat least the accumulation of moisture on the display screen of theelectronic device. For example, due to the accumulation of the moistureon the display screen, the worker may not be able to read the tasks onthe display screen. Further, the worker may not be able to provideinputs through the display screen, as content displayed on the displayscreen is hazy (due to accumulation of moisture) and/or the moisture onthe display screen presents the touch sensors from reading touch inputs.This may hamper the overall productivity and efficiency of the workerperforming a task in such work environments.

According to one or more embodiments described herein, a display screenis disclosed. The display screen includes a photo transceiver layer. Thephoto transceiver layer includes a plurality of photo transmitters suchas LED or any other light source. Further, the photo transceiver layerincludes a plurality of sensors. Additionally, the display screenincludes a glass substrate layer disposed on top of the phototransceiver layer.

The plurality of photo transmitters may be configured to generate aplurality of light signals that passes through the glass substratelayer. When moisture accumulates/forms on a surface of the glasssubstrate layer, a portion of the plurality of light signal may getreflected back from the surface of the glass substrate layer. Aplurality of second sensors (e.g., photo detectors) may detect thisreflected portion of light signal and may accordingly generate a secondsignal based on the reflected portion of light signal. The second signalis indicative of a measurement of transmissivity/reflectivity of theglass substrate layer. If the transmissivity/reflectivity measurement ofthe glass substrate layer satisfies a transmissivity/reflectivitythreshold, a controller in the display screen may determine that themoisture has accumulated on the glass substrate layer.

Thereafter, the controller of the display screen may be configured todetermine a first area on the display screen where the moisture hasaccumulated based on the location of one or more second sensors thathave received the reflected portion of the light signal. Afterdetermining the first area, the controller may be configured to alterone or more electric currents supplied to a set of photo transmittersassociated with the first area on the display screen. This causes theone or more photo transmitters to generate sufficient heat to evaporatethe accumulated moisture on the first area on the display screen.

Because of the presence of the one or more second sensors in the displayscreen, the controller in the display screen is able to determine theexact location of moisture accumulation. Further, because the controllerutilizes the photo transmitters in the display screen to heat thespecific portions of the display screen, no additional heating elementis required to heat the display screen in order to remove anyaccumulated moisture. Hence, the cost of the proposed solution is lessin comparison to the conventional display screen.

FIG. 1 illustrates an example material handling environment 100,according to one or more embodiments described herein. The materialhandling environment 100 may refer to environments related to, but notlimited to, manufacturing of the items, inventory storage of the items,packaging and unpackaging of the items, preparing customer orders,recording items related information based on scanning and identificationof the items, and shipment processing (including shipping and logisticsdistribution of the items). In such environments, many workers performdifferent operations, which may involve handling of the items duringvarious phases (including, but not limited to, accumulation, sortation,scanning and identification, packaging and shipment preparation etc.),of overall operation cycle of the material handling environment 100. Forexample, the workers are involved in manual packaging and unpackaging ofthe items while preparing customer orders for shipping. In anotherexample, the workers may handle placing of the items in an accumulationzone of a conveyor system for automated packaging of the items. In someenvironments, workers may use electronic devices (e.g., an electronicdevice 102) such as personal digital assistants (PDAs) or mobile devicesthat may be communicatively connected to a headset and a server (e.g., aserver 106), for receiving automated or voice directed instructions forperforming various operations including scanning and identification oflabels, such as barcodes, RFID tags, etc. affixed on the items forshipment preparation. Thus, in these environments, many workers areusually involved in performing various operations involving handlingitems and performing operations including interaction with differentmachines, such as an accumulator, a dimensioner, a scanning andidentification device, etc., for shipment processing and transportation.As illustrated in FIG. 1, the material handling environment 100 includesthe electronic device 102, a network 104, the server 106. The electronicdevice 102 and the server 106 are communicatively coupled with eachother through the network 104.

In an example embodiment, the electronicdevice 102 may include a display screen 110, as is further described inconjunction FIG. 2. The display screen 110 may be configured to displayinformation/content to the operator 108 of the electronic device 102.For example, the electronic device 102 may be configured to displayinstructions on the display screen 110 to the operator 108 based onwhich the operator 108 of the electronic device 102 may perform a task.Some examples of the electronic device 102 may include, but are notlimited to, a mobile phone, a computer, a laptop, a bar code scanner,palm top computers, PDA, and/or any other device that includes thedisplay screen 110. The structure of the electronic device 102 isdescribed later in conjunction with FIG. 2.

The network 104 may be any means such as a device or circuitry embodiedin either hardware or a combination of hardware and software that isconfigured to receive and/or transmit data from/to various devices ofthe material handling environment 100 (e.g., the electronic device 102and the server 106). In this regard, the network 104 may include, forexample, a network interface for enabling communications with a wired orwireless communication network. For example, the network 104 may includeone or more network interface cards, antennae, buses, switches, routers,modems, and supporting hardware and/or software, or any other devicesuitable for enabling communications via a network. Additionally, oralternatively, the network 104 may include the circuitry for interactingwith the antenna(s) to cause transmission of signals via the antenna(s)or to handle receipt of signals received via the antenna(s). Suchsignals may be transmitted using one or more communication protocols,such as Bluetooth® v1.0 through v3.0, Bluetooth Low Energy (BLE),infrared wireless (e.g., IrDA), ultra-wideband (UWB), induction wirelesstransmission, Wi-Fi, Near Field Communications (NFC), TCP/IP, UDP, 2G,3G, 4G, 5G, Worldwide Interoperability for Microwave Access (WiMAX), orother proximity-based communications protocols.

The server 106 may include suitable logic and/or circuitry that may beconfigured to receive/transmit data from/to the electronic device 102through the network 104. For example, the server 106 may be configuredto transmit instruction related to the task to be performed by theoperator 108 of the electronic device 102. In an example embodiment, theserver 106 may be implemented using various application servers such as,but are not limited to, JBOSS™, Apache™, Apache-Tomcat™, and/or thelike.

FIG. 2 illustrates a perspective view 200 of the electronic device 102,according to one or more embodiments described herein. In an exampleembodiment, the electronic device 102 includes a housing 202, thedisplay screen 110, and one or more buttons 206 a, 206 b, 206 c and 206d. The housing 202 may be configured receive the one or more electroniccircuits (not shown) such as, but not limited to, a processor, a memoryunit, input/output device interface, battery, and/or the like that mayenable the electronic device 102 to display content (e.g., task to beperformed by the operator 108) on the display screen 110. Further, thehousing 202 may be configured to receive the display screen 110 and theone or more buttons 206 a, 206 b, 206 c and 206 d.

The display screen 110 may include suitable logic, circuitry,interfaces, and/or code that may facilitate rendering or displaying ofthe content on the display screen 110. In an example embodiment, thedisplay screen 110 may be realized through technologies such as, CathodeRay Tube (CRT) based display, Liquid Crystal Display (LCD), LightEmitting Diode (LED) based display, Organic LED display technology, andRetina display technology. In some embodiments, the display screen 110may further include a touch panel, such as a thermal touch panel, acapacitive touch panel, and/or a resistive touch panel, which may enablethe operator 108 to provide inputs to the electronic device 102 and/orthe display screen 110. The structure of the display screen 110 isfurther described in conjunction with FIG. 3A and FIG. 3B.

In an example embodiment, the one or more buttons 206 a, 206 b, and 206c are configured to facilitate the operator 108 to provide inputs to theelectronic device 102. For example, the operator 108 may be configuredto press the button 206 c to reduce the volume of the audio signalgenerated by the electronic device 102. In another example, the operator108 may be configured to press the button 206 b to switch ON or switchOFF the display screen 110. In yet another example, the operator 108 maybe configured to press the button 206 b to switch ON or switch OFF theelectronic device 102.

FIG. 3A illustrates an exploded view 300 a of the display screen 110,according to one or more embodiments described herein. In an exampleembodiment, the exploded view 300 of the display screen 110 illustratesthat the display screen 110 includes a photo transceiver layer 302, atouch panel 304, a glass substrate layer 306, and an electronic circuitlayer 308. In an example embodiment, the photo transceiver layer 302 andthe touch panel 304 are communicatively coupled to the electroniccircuit layer 308.

The photo transceiver layer 302 corresponds to a layer that is capableof generating and detecting light signals. For example, the phototransceiver layer 302 includes a plurality of photo transmitters 314that may be capable of generating light signals based on electricalsignals received from the electronic circuit layer 308. In someexamples, the generated light signals may be representative of thecontent displayed on the display screen 110. In an example embodiment,the plurality of photo transmitters 314 may be fabricated uniformly onthe photo transceiver layer 302 in such a manner that a phototransmitter of the plurality of photo transmitters is equally spacedapart from adjacent photo transmitters of the plurality of phototransmitters. Some examples of the plurality of photo transmitters 314may include, but are not limited to, a Light Emitting Diode (LED), aLASER, and/or the like.

Further, to enable detection of the light signals, the photo transceiverlayer 302 includes a plurality of second sensors 316 that are fabricatedon the photo transceiver layer 302 in such a manner that the pluralityof second sensors 316 is positioned among the plurality of phototransmitters 314. In some examples, the plurality of the second sensors316 are positioned between two adjacent photo transmitters of theplurality of photo transmitters 314. For example, the second sensor 316a is positioned between the photo transmitters 314 a and the phototransmitter 314 b. In some examples, the scope of the disclosure is notlimited to the second sensor 316 a of the plurality of second sensors316 being positioned between the two adjacent photo transmitters (e.g.,314 a and 314 b). In an alternative embodiment, the plurality of secondsensors 316 may be positioned in the photo transceiver layer 302 in anyother uniform pattern, without departing from the scope of thedisclosure. For example, the plurality of second sensors 316 may bepositioned on the photo transceiver layer 302 in such a manner that thesecond sensor 316 a of the plurality of second sensors 316 is positionedafter every predetermined count of photo transmitters. For example, thesecond sensor 316 a may be positioned on the photo transceiver layer 302after every two photo transmitters. Similarly, other uniform patterns ofpositioning of the plurality of second sensors 316 may be contemplated,without departing from the scope of the disclosure.

In an example embodiment, the plurality of second sensors 314 maycorrespond to a plurality of light sensors that may be configured togenerate a plurality of second signals based on detection of lightsignals. In an example embodiment, a second signal may correspond to avoltage signal that has one or more characteristics such as, but notlimited to, an amplitude and a frequency. In an example embodiment, ameasurement of the one or more characteristics of the second signal maybe indicative of an intensity of light signal detected by the secondsensor of the plurality of second sensors 316.

In some examples, the plurality of second sensors 316 may correspond toat least one of a photodetector, a photodiode, or a photo resistor thatmay detect the plurality of light signals received from an ambientenvironment of the display screen 110 (e.g., external light source). Insuch an example, the plurality of second sensors 316 may be configuredto detect the plurality of light signals that originate in the ambientenvironment around the display screen 110 and that passes through theglass substrate layer 306 and the touch panel 304. Therefore, theintensity of the plurality of light signals detected by the plurality ofsecond sensors 316 is dependent on a transmissivity of the glasssubstrate layer 306 and the touch panel 304 (hereinafter referred to asthe transmissivity of the display screen 110). In an example embodiment,the transmissivity of the display screen 110 may correspond to ameasurement of the intensity of a light signal that the display screen110 allows to pass through. Because the measurement of the one or morecharacteristics associated with each of the plurality of second signalsis indicative of the intensity of the light signal detected by theplurality of second sensors 316, the measurement of the one or morecharacteristics associated with the plurality of the second signalscorresponds to the transmissivity measurement of the display screen 110.

In another example, the plurality of second sensors 316 may beconfigured to detect a portion of the plurality of light signalsgenerated by the plurality of photo transmitters 314. In an exampleembodiment, the portion of the plurality of light signals generated bythe plurality of photo transmitters 314 may correspond to the lightsignals that are reflected from the glass substrate layer 306.Therefore, in such an example, the plurality of second signals generatedby the plurality of second sensors 316 may be indicative of areflectivity measurement of the glass substrate layer 306 (hereinafterreferred to as reflectivity of the display screen 110). Therefore, themeasurement of the one or more characteristics associated with theplurality of second signals, in such an embodiment, corresponds to thereflectivity measurement of the display screen 110.

In some examples, the scope of the disclosure is not limited to theplurality of second sensors 316 corresponding to the light sensors thatare configured to determine the transmissivity measurement orreflectivity measurement. In an alternative embodiment, the plurality ofsecond sensors 316 may correspond to moisture sensors that areconfigured to detect accumulation of moisture on the display screen 110,without departing from the scope of the disclosure.

In some examples, as discussed above, each second sensor of theplurality of second sensors 316 are fixedly positioned among theplurality of photo transmitters 314 on the photo transceiver layer 302.Therefore, each second sensor of the plurality of second sensors 316 mayreceive the plurality of light signals only through a specific portionof the glass substrate layer 306. Accordingly, the plurality of secondsignals generated by the plurality of second sensors 316 is indicativeof the transmissivity or reflectivity measurement of correspondingspecific portion of the glass substrate layer (hereinafter referred toas measurement area on the display screen 110), as is further describedin conjunction with FIG. 6. Because the plurality of second sensors 316are positioned throughout the span of the display screen 110 (e.g.,throughout the span of the photo transceiver layer 302) and each secondsensor of the plurality of second sensors 316 receives light signal fromthe specific portion on the glass substrate layer (i.e., the measurementarea), the display screen 110 is said to be divided into one or moremeasurement areas.

The touch panel 304 may correspond to a transparent layer that isdisposed on the photo transceiver layer 302. In an example embodiment,the touch panel 304 includes a plurality of first sensors 318 that isconfigured to detect a touch input from the operator 108 of theelectronic device 102. For example, the plurality of first sensors 318may correspond to an array of capacitive sensors that may be configuredto detect the touch input based on a change in the capacitance of thearray of capacitive sensors. In another example, the plurality of firstsensors 318 may correspond to a plurality of resistive sensors that maybe configured detect the touch input based on a change in theresistivity of the plurality of resistive sensors. In an exampleembodiment, each first sensor of the plurality of first sensors 318 maybe configured to generate one or more first signals based on thedetection of the touch input, as is further described in conjunctionwith FIG. 14. Further, the first signal may be indicative of a locationon the touch panel 304 (hereinafter referred to as the location of thedisplay screen 110), which has received the touch input, as is furtherdescribed in conjunction with FIG. 16. Further, the touch panel 304 maybe configured to transmit the first signal to the electronic circuitlayer 308.

In an example embodiment, the glass substrate layer 306 may correspondto a transparent protective glass that is disposed on the touch panel304. The glass substrate layer 306 may protect the touch panel 304, thephoto transceiver layer 302, and/or the electronic circuit layer 308from damage. In some examples, the scope of the disclosure is notlimited to the glass substrate layer 306 being disposed on top of thetouch panel 304. In an alternative embodiment, the glass substrate layer306 and the touch panel 304 may be fabricated on a single layer. In suchan embodiment, the touch panel 304 may be embedded in the glasssubstrate layer 306. Some examples of the glass substrate layer 306 maybe include, but not limited to GORILLA GLASS™.

In an example embodiment, the electronic circuit layer 308 maycorrespond to a printed circuit board (PCB) that is communicativelycoupled with the photo transceiver layer 302 and the touch panel 304. Insome example embodiments, the electronic circuit layer 308 may include aplurality of driver circuits, interfaces, controllers, that enables theelectronic circuit layer 308 to communicate with the photo transceiverlayer 302 and the touch panel 304. In an example embodiment, theelectronic circuit layer 308 may further include a control system 310that is configured to control the operation of the display screen 110.The operation and structure of the control system 310 is described inconjunction with FIG. 4.

FIG. 3B illustrates a sectional view 300 b of the display screen 110,according to one or more embodiments described herein. The sectionalview 300 b depicts that the control system 310 is communicativelycoupled with the photo transceiver layer 302 and the touch panel 304.More particularly, the control system 310 is communicatively coupledwith the plurality of photo transmitters 314 and the plurality of secondsensors 316 in the photo transceiver layer 302.

FIG. 5 illustrates a flowchart 500 of a method for operating the displayscreen 110, according to one or more embodiments described herein.

At step 502, the display screen 110 includes means, such as the controlsystem 310, the controller 402, and/or the like, for detecting an eventon the display screen 110. As discussed, the event may correspond to atleast one of detection of moisture accumulation on the display screen110, the temperature of the ambient environment around the displayscreen 110 satisfying a temperature threshold, reception of the touchinput on the display screen 110, and/or the display of the predeterminedcontent on the display screen 110. The detection of the moistureaccumulation is described later in conjunction with FIG. 6. Further, thereception of the touch input is described later in conjunction with FIG.14. Further, the detection of the temperature of the ambient environmentsatisfying the temperature threshold is described later in conjunctionwith FIGS. 11, 15, and 17. Furthermore, the display of the predeterminedcontent is described later in conjunction with FIG. 20.

At step 504, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first moisture detection unit 412,and/or the like, for identifying the one or more first areas from theone or more measurement areas based on the detected event. Theidentification of the one or more first areas is described later inconjunction with FIGS. 6-21

At step 506, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first photo transceiver interfaceunit 410, and/or the like, for altering the electric current supplied tothe one or more photo transmitters associated with the one or more firstareas. The altering of the electric current supplied to the one or morephoto transmitters is described later in conjunction with FIG. 6.

FIG. 6 illustrates a flowchart 600 of a method for operating the displayscreen 110 based on detection of event of moisture accumulation on thedisplay screen 110, according to one or more embodiments describedherein.

At step 602, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first photo transceiver interfaceunit 410, and/or the like, for receiving the plurality of second signalsfrom the plurality of second sensors 316. As discussed above, eachsecond signal of the plurality of second signals corresponds to thevoltage signal that is indicative of the transmissivity/reflectivitymeasurement of the glass substrate layer 306. In an example embodiment,the one or more characteristics of the plurality of second signals (suchas the amplitude and the frequency) are indicative of the intensity ofthe light signal detected by the plurality of second sensors 316.Because the intensity of the light signal detected by the plurality ofsecond sensors is dependent on the transmissivity/reflectivity of theone or more respective measurement areas on the display screen 110,therefore, the measurement of the one or more characteristics of theplurality of second signals corresponds to thetransmissivity/reflectivity measurement of the one or more respectivemeasurement areas. For example, variation in the measurement of the oneor more characteristics of the plurality of second signals may beindicative of the variations in the transmissivity/reflectivitymeasurement of the one or more respective measurement areas on thedisplay screen 110. The variations in the plurality of second signalsare further described in conjunction with FIG. 7.

FIG. 7 is an example illustration 700 depicting the plurality of secondsignals and the one or more respective measurement areas on the displayscreen 110, according to one or more embodiments described herein. Theillustration 700 depicts that the display screen 110 includes ameasurement area 702 a, a measurement area 702 b, and a measurement area702 c. In an example embodiment, as discussed above, each of the one ormore measurement areas is defined as the portion on the display screenthrough which a second sensor of the plurality of second sensors 316receives and detects the light signal. Therefore, each of themeasurement area 702 a, the measurement area 702 b, and the measurementarea 702 c, has an associated second sensor of the plurality of secondsensors 316. Further, the second sensors associated with the measurementareas 702 a, 702 b, and 702 c generate the second signals indicative ofthe transmissivity/reflectivity measurement of the respectivemeasurement areas 702 a, 702 b, and 702 c. For example, the secondsensor associated with the measurement area 702 a generates the secondsignal, depicted by the graphical representation 704 a. Similarly, thesecond sensors associated with the measurement areas 702 b and 702 cgenerate the second signals depicted by the graphical representations704 b and 704 c, respectively. Each of the graphical representations 704a, 704 b, and 704 c has an X-axis (e.g., 708) and a Y-axis (e.g., 706).The X-axis (e.g., 708) may represent a time at which the first phototransceiver interface unit 410 receives the plurality of second signals.The Y-axis (e.g., 706) represents the amplitude of the plurality ofsecond signals. Further, the graphical representations 704 a, 704 b, and704 c include curves 710 a, 710 b, and 710 c, respectively. Each of thecurves 710 a, 710 b, and 710 c is representative of the variation in theamplitude of the second signals (represented by the graphicalrepresentations 704 a, 704 b, and 704 c).

It can be observed that the amplitude of the curve 710 b (depicting thesecond signal corresponding to the measurement area 702 b) decreases asthe time continues, and the amplitude of the curves 710 a and 710 cremains constant. The reducing amplitude of the curve 710 b may beindicative of the variation in the transmissivity/reflectivitymeasurement of the measurement area 702 b. For example, reducingamplitude of the curve 710 b may depict a reducing transmissivity of thedisplay screen 110. Further, because the amplitude of the curves 710 aand 710 c remain constant, the transmissivity/reflectivity measurementof the measurement areas 702 a and 702 c is constant.

In some examples, the variation in the transmissivity/reflectivitymeasurement of the measurement area 702 b may be due to moistureaccumulation in the measurement area 702 b. In some examples, in aninstance in which the moisture gets accumulated on the display screen110, the transmissivity of the display screen 110 decreases while thereflectivity of the display screen 110 increases. Therefore, in someimplementations, where the second signal corresponds to the reflectivitymeasurement, the amplitude of the second signal may depict an increasewhen the moisture gets accumulated on the display screen 110. Similarly,where the second signal corresponds to the transmissivity measurement,the amplitude of the second signal may depict a decrease (such as thecurve 710 b) when the moisture gets accumulated on the display screen110.

The moisture accumulation may occur in certain environmental conditionssuch as environment temperature dropping to below zero degree Celsius.Because the transmissivity/reflectivity measurement of a measurementarea of the one or more measurement areas varies upon moistureaccumulation, by monitoring the transmissivity/reflectivity measure, themoisture accumulation on the display screen 110 may be detected, as isfurther described in the step 606 of FIG. 6. The variation in thetransmissivity/reflectivity measurement of the measurement area 702 bdue to accumulation of the moisture is further illustrated in FIGS. 10Aand 10B.

Referring back to FIG. 6, at step 604, the display screen 110 includesmeans, such as the control system 310, the controller 402, the firstphoto transceiver interface unit 410, and/or the like, for analyzingeach second signal of the plurality of second signals to determine themeasurement of the one or more characteristics of each second signal ofthe plurality of second signals. As discussed above, the one or morecharacteristics of each of the plurality of second signals include theamplitude of the second signal and the frequency of the second signal.

To determine the amplitude measurement of the second signal of theplurality of second signals, the first photo transceiver interface unit410 may be configured to determine an average amplitude of the secondsignals (received during the time duration (e.g., depicted by the X-axis708)). Thereafter, the first photo transceiver interface unit 410 maydetermine the determined average amplitude as the amplitude measurementof the second signal. In an alternative embodiment, the first phototransceiver interface unit 410 may determine the amplitude measurementof the second signal based on the real time or current amplitudemeasurement of the second signal. For instance, the amplitudemeasurement of the second signal at a time instance t₁ is V₁ and theamplitude measurement of the second signal at a current time instant isV₂, the first photo transceiver interface unit 410 may determine theamplitude V₂ as the amplitude measurement of the second signal.

To determine the frequency measurement of the second signal, the firstphoto transceiver interface unit 410 may be configured to transform thesecond signal to a frequency domain second signal using one or moresignal processing techniques such as, but not limited to, DFT, DTFT,and/or the like. In some examples, the frequency domain second signalmay be deterministic of various frequencies present in the secondsignal. Thereafter, the first photo transceiver interface unit 410 maydetermine the frequency measurement of the second signal based on anaverage of the various frequencies present in the second signal. In anexample embodiment, the first photo transceiver interface unit 410 maybe configured to analyze the other second signals of the plurality ofsecond signals in a similar manner to determine the measurement of theone or more characteristics of the other second signals.

As discussed above, the measurement of the one or more characteristicsof the second signal (i.e., the amplitude measurement and the frequencymeasurement) corresponds to the transmissivity/reflectivity measurementof the respective measurement area on the display screen 110. Forexample, the amplitude measurement of the second signal may correspondto the transmissivity/reflectivity measurement of the respectivemeasurement area. In another example, the frequency measurement of thesecond signal may correspond to the transmissivity/reflectivitymeasurement of the respective measurement area. In yet another example,a combination of the amplitude measurement and the frequency measurementof the second signal corresponds to the transmissivity/reflectivitymeasurement of the respective measurement area.

At step 606, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first moisture detection unit 412,and/or the like, for identifying the one or more first areas of the oneor more measurement areas. In some examples, the one or more first areasmay correspond to measurement areas where the moisture may haveaccumulated. The identification of the one or more first areas isfurther described in conjunction with FIG. 8.

FIG. 8 illustrates a flowchart 800 of a method for identifying the oneor more first areas of the one or more measurement areas, according toone or more embodiments described herein.

At step 802, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first moisture detection unit 412,and/or the like, for determining whether each of the one or moremeasurement areas has been checked for moisture accumulation. In anexample embodiment, if the first moisture detection unit 412 determinesthat the moisture accumulation has been checked for each of the one ormore measurements areas, the first moisture detection unit 412 may beconfigured to perform the step 608. However, if the first moisturedetection unit 412 determines that not each of the one or moremeasurement areas has been checked for moisture accumulation, the firstmoisture detection unit 412 may be configured to perform the step 804.

At step 804, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first photo transceiver interfaceunit 410, the first moisture detection unit 412, and/or the like, fordetermining whether the display screen 110 is switch ON. As discussedabove, the operator 108 of the electronic device 102 may provide inputto switch ON the display screen 110 or switch OFF the display screen110. Accordingly, based at least on the reception of the input from theoperator 108, the first photo transceiver interface unit 410 may beconfigured to determine whether the display screen 110 is switched ON.In alternative embodiment, the first photo transceiver interface unit410 may be configured to determine whether the display screen 110 hasbeen switched ON based on whether the electric current is being suppliedto each of the plurality of photo transmitters 314. If the first phototransceiver interface unit 410 determines that the display screen 110 isswitched ON, the controller 402 may be configured to perform the step806.

At step 806, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first moisture detection unit 412,and/or the like, for determining whether the reflectivity measurementassociated with a measurement area of the one or more measurement areasatisfies (e.g. is greater than) a reflectivity threshold. In an exampleembodiment, because the display screen 110 is switched ON, the pluralityof photo transmitter 314 may be configured to generate the lightsignals. Major portion of the generated light signal is generallyexpected to pass through the glass substrate layer 306. However, inscenarios, where the moisture has accumulated on the display screen 110,some portion of the light signal may get reflected back towards thephoto transceiver layer 302. Further, the plurality second sensors maydetect the reflected portion of the light signals. Accordingly, theamplitude of the plurality of second signals will depict an increase(because of the detection of the reflected portion of the light signal).Further, the amplitude of the second signal may be indicative of thereflectivity measurement of the display screen 110. Accordingly, whenthe display screen 110 is switched ON, increase in the amplitude of theplurality of second signals may depict moisture accumulation. Hence, atstep 806, the first moisture detection unit 412 determines whether thereflectivity measurement associated with the measurement area satisfies(e.g. is greater than) the reflectivity threshold.

As discussed above, the reflectivity measurement of the measurement areacorresponds to the measurement of the one or more characteristics of thesecond signal generated by the second sensor associated with themeasurement area. In some examples, the reflectivity threshold maycorrespond to a first threshold measurement of the one or morecharacteristics of the second signal. Therefore, in other words, thefirst moisture detection unit 412, at step 804, may determine whetherthe measurement of the one or more characteristics of the second signal(corresponding to the measurement area) satisfies (e.g. is greater than)the first threshold measurement of the one or more characteristics. Thedetermination of the step 806 is further described in conjunction withFIG. 9.

FIG. 9 illustrates a flowchart 900 of a method for determining whetherthe reflectivity measurement associated with the measurement areasatisfies (e.g. is greater than) the reflectivity threshold.

At step 902, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first moisture detection unit 412,and/or the like, for determining whether the amplitude of the secondsignal satisfies (e.g., greater than) a first amplitude threshold (i.e.,the threshold measurement of the one or more characteristics). In anexample embodiment, the first amplitude threshold may correspond to thefirst threshold measurement of the one or more characteristics. If thefirst moisture detection unit 412 determines that the amplitude of thesecond signal does not satisfy (e.g., is less than) the first amplitudethreshold, the first moisture detection unit 412 may be configured toperform the step 906. However, if the first moisture detection unit 412determines that the amplitude measurement of the second signal satisfies(e.g. is greater than) the first amplitude threshold, the first moisturedetection unit 412 may be configured to perform the step 904.

At step 906, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first moisture detection unit 412,and/or the like, for determining that the measurement of the one or morecharacteristics of the second signal is does not satisfy (e.g., lessthan) the first threshold measurement of the one or morecharacteristics.

At step 904, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first moisture detection unit 412,and/or the like, for determining whether a predetermined time period haselapsed since a time instant at which the amplitude measurement isdetermined to satisfy (e.g. is greater than) the first amplitudethreshold. If the first moisture detection unit 412 determines that thepredetermined time period has elapsed, the first moisture detection unit412 may be configured to perform the step 908. However, if the firstmoisture detection unit 412 determines that the predetermined timeperiod has not elapsed, the first moisture detection unit 412 may beconfigured to repeat the step 902. By performing the step 904, the firstmoisture detection unit 412 checks whether the amplitude of the secondsignal satisfies (e.g. is greater than) the first amplitude thresholdfor the predetermined time period. Accordingly, by performing the step904, the first moisture detection unit 412 avoids false determination ofthe amplitude of the second signal satisfying (e.g. greater than) thefirst amplitude threshold. For example, due to noise in the secondsignal, the amplitude measurement at a time instant t₁ satisfies (e.g.is greater than) the first amplitude threshold momentarily. However, inthe subsequent time instant t₂, the amplitude measurement does notsatisfy (e.g., less than) the first amplitude threshold. Therefore, hadthe moisture detection unit 412 not performed the step 904, the moisturedetection unit 412 would have, incorrectly, performed the step 908.

At step 908, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first moisture detection unit 412,and/or the like, for determining that the measurement of the one or morecharacteristics of the second signal satisfies (e.g. is greater than)the first threshold measurement of the one or more characteristics.

In some examples, the scope of the disclosure is not limited to onlycomparing the amplitude of the second signal with the first amplitudethreshold to determine whether the measurement of the one or morecharacteristics satisfies (e.g. is greater than) the first thresholdmeasurement of the one or more characteristics. In alternativeembodiment, the first moisture detection unit 412 may be configured tocompare the frequency measurement of the second signal with a firstfrequency threshold to determine whether the measurement of the one ormore characteristics satisfies (e.g. is greater than) the firstthreshold measurement of the one or more characteristics. In such animplementation, the first frequency threshold corresponds to the firstthreshold measurement of the one or more characteristics. In yet anotherembodiment, the first moisture detection unit 412 may be configured tocompare both the amplitude measurement and the frequency measurement ofthe second signal with the first amplitude threshold and the firstfrequency threshold, respectively, to determine whether the measurementof the one or more characteristics satisfies (e.g. is greater than) thefirst threshold measurement of the one or more characteristics. In suchan embodiment, the first moisture detection unit 412 may determine thatthe measurement of the one or more characteristics satisfies (e.g. isgreater than) the first threshold measurement of the one or morecharacteristics only when both the amplitude measurement and thefrequency measurement of the second signal satisfy (e.g. is greaterthan) the first amplitude threshold and the first frequency threshold,respectively. Further, in such an embodiment, both the first amplitudethreshold and the first frequency threshold correspond to the firstmeasurement threshold of the one or more characteristics.

Referring back to the step 806, if the first moisture detection unit 412determines that the measurement of the one or more characteristics ofthe second signal satisfies (e.g. is greater than) the first thresholdmeasurement of the one or more characteristics, the first moisturedetection unit 412 may determine the reflectivity measurement of themeasurement area satisfies (e.g. is greater than) the reflectivitythreshold. Accordingly, the first moisture detection unit 412 may beconfigured to perform the step 810. However, if the first moisturedetection unit 412 determines that the measurement of the one or morecharacteristics of the second signal is does not satisfy (e.g., lessthan) the first threshold measurement of the one or morecharacteristics, the first moisture detection unit 412 may determine thereflectivity measurement of the measurement area is does not satisfy(e.g., less than) the reflectivity threshold. Accordingly, the firstmoisture detection unit 412 may be configured to repeat the step 802.

Referring back to step 804, if the first photo transceiver interfaceunit 410 determines that the display screen 110 is switched OFF, thecontroller 402 may be configured to perform the step 808. At step 808,the display screen 110 includes means, such as the control system 310,the controller 402, the first moisture detection unit 412, and/or thelike, for determining whether the transmissivity measurement associatedwith the measurement area of the one or more measurement area satisfy(e.g., less than) the transmissivity threshold. In an exampleembodiment, because the display screen 110 is switched OFF, theplurality of photo transmitter 314 may not be generating the lightsignals. The plurality of second sensors 316 may be receiving lightsignals from the ambient environment around the display screen 110.Major portion of the light signal from the ambient environment generallypass through the glass substrate layer 306 and is detected by theplurality of second sensors 316. However, in scenarios, where themoisture has accumulated on the display screen 110, the light signalsfrom the ambient environment are not able to pass through the glasssubstrate layer 306. This, in some examples, result in a dip in theamplitude of the plurality of second signals generated by the secondsensors 316. Therefore, when the display screen 110 is switched OFF, thedip in the amplitude of the plurality of second signals may depictmoisture accumulation. Hence, at step 808, the first moisture detectionunit 412 determines whether the transmissivity measurement associatedwith the measurement area satisfies (e.g., less than) the transmissivitythreshold.

In some examples, the first moisture detection unit 412 may determinewhether the amplitude measurement of the second signal satisfies (e.g.,less than) a second amplitude threshold. If the first moisture detectionunit 412 determines that the amplitude measurement of the second signalsatisfies (e.g., less than) the second amplitude threshold, the firstmoisture detection unit 412 may determines that the measurement of theone or more characteristics satisfies (e.g., less than) a secondthreshold measurement of the one or more characteristics. In such animplementation, the second amplitude threshold corresponds to the secondthreshold measurement of the one or more characteristics. In alternativeembodiment, the first moisture detection unit 412 may be configured todetermine whether the frequency measurement of the second signalsatisfies (e.g., less than) a second frequency threshold, to determinewhether the measurement of the one or more characteristics satisfies(e.g., less than) the threshold measurement of the one or morecharacteristics. In such an implementation, the second frequencythreshold corresponds to the second threshold measurement of the one ormore characteristics. In yet another embodiment, the first moisturedetection unit 412 may be configured to determine whether both theamplitude measurement and the frequency measurement of the second signalsatisfy (e.g., less than) the second amplitude threshold and the secondfrequency threshold, respectively, to determine whether the measurementof the one or more characteristics satisfies (e.g., less than) thesecond threshold measurement of the one or more characteristics. In suchan embodiment, the first moisture detection unit 412 may determine thatthe measurement of the one or more characteristics satisfies (e.g., lessthan) the second threshold measurement of the one or morecharacteristics only when both the amplitude measurement and thefrequency measurement of the second signal satisfy (e.g., less than) thesecond amplitude threshold and the second frequency threshold,respectively.

In an example embodiment, the first threshold measurement of the one ormore characteristics is different from the second threshold measurementof the one or more characteristics. For example, the value of the firstamplitude threshold is different from the second amplitude threshold. Inan example embodiment, if the amplitude measurement of the second signalis between the first amplitude threshold and the second amplitudethreshold, the moisture detection unit 412 may determine that nomoisture as accumulated on the display screen 110. In an alternativeembodiment, the first threshold measurement of the one or morecharacteristics is equal to the second threshold measurement of the oneor more characteristics, without departing from the scope of thedisclosure. For example, the value of the first amplitude threshold isequal to the second amplitude threshold.

In an example embodiment, if at step 808, the first moisture detectionunit 412 determines that the transmissivity measurement associated withthe measurement area satisfies (e.g., less than) the secondtransmissivity threshold, the first moisture detection unit 412 may beconfigured to perform the step 810. However, if the first moisturedetection unit 412 determines that the transmissivity measurementassociated with the measurement area does not satisfy (e.g., greaterthan) the transmissivity threshold, the first moisture detection unit412 may be configured to repeat the step 802.

At the step 810, the display screen 110 includes means, such as thecontrol system 310, the controller 402, the first moisture detectionunit 412, and/or the like, for detecting the event of moistureaccumulation in the measurement area. Accordingly, at step 812, thedisplay screen 110 includes means, such as the control system 310, thecontroller 402, the first moisture detection unit 412, and/or the like,for classifying the measurement area as the first area. Thereafter, thefirst moisture detection unit 412 may be configured to repeat the step802.

In an example embodiment, the first moisture detection unit 412 may beconfigured to perform the method described in the flowchart 800 untilthe first moisture detection unit 412 checks each of the one or moremeasurement areas for moisture accumulation. After performing the methoddescribed in the flowchart 800, the first moisture detection unit 412may have identified the one or more first areas of the one or moremeasurement areas. In some examples, the first moisture detection unit412 may be configured to store the information pertaining to the one ormore first areas in the first memory device 404. In an exampleembodiment, the information pertaining to the one or more first areas ofthe display screen 110 may include the location of the one or more firstareas on the display screen 110. In an example embodiment, the firstmoisture detection unit 412 may be configured to determine the locationof the one or more first areas from the data information pertaining tothe each of the one or more measurement areas stored in the first memorydevice 404, as is illustrated above in table 2.

In some examples, the scope of the disclosure is not limited to checkeach of the one or more measurement areas for moisture accumulation toidentify the one or more first areas. In an alternative embodiment, thecontroller 402 may be configured to perform the steps of flowchart 800in parallel for each of the one or more measurement area. In such anembodiment, the controller 402 may not perform the step 802, as each ofthe one or more measurement areas are being checked for moistureaccumulation in parallel. Further, in such an implementation, as soon asthe controller 402 determines moisture accumulation in a measurementarea of the one or more measurement areas, the controller 402 performsthe step 608 for the measurement area.

Referring back to FIG. 6, at the step 608, the display screen 110includes means, such as the control system 310, the controller 402, thefirst photo transceiver interface unit 410, and/or the like, foridentifying the one or more photo transmitters of the plurality of phototransmitters 314. In an example embodiment, the one or more phototransmitters may correspond to the photo transmitters that correspond tothe one or more first areas. To identify the one or more phototransmitters, the first photo transceiver interface unit 410 may beconfigured to retrieve the data pertaining to the one or more firstareas from the first memory device 404. As discussed above, theinformation data pertaining to the one or more first areas include thelocation information of the one or more first areas on the displayscreen 110. Further, as discussed, the location information correspondsto a set of coordinates on the display screen 110 that define each ofthe one or more first areas on the display screen 110. In some examples,the set of coordinates may define the periphery of the one or more firstareas on the display screen 110. For example, if the set of coordinatesof a first area includes (0,0), (3,3), (0,3), and (3,0), the coordinates(0,0), (3,3), (3,0), and (0,3) depict the periphery of the first area.

After identifying the location information pertaining to the one or morefirst areas, the first photo transceiver interface unit 410 may beconfigured to correlate the location information of the one or morefirst areas with the location of the plurality of the photo transmitters314 to identify the one or more photo transmitters of the plurality ofthe photo transmitters 314 that are included in the one or more firstareas. For example, if the first area has the coordinates (0,0), (3,3),(0,3), and (3,0) and the first photo transmitter and the second phototransmitter in the plurality of photo transmitter 314 has coordinates(2,2), and (5,2), the first photo transceiver interface unit 410determines that the first photo transmitter located at (2,2) is includedin the first area while the second photo transmitter located at (5,2) isnot included in the first area. Further, the first photo transceiverinterface unit 410 may be configured to determine the first phototransmitter as one of the one or more photo transmitters.

At step 610, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first photo transceiver interfaceunit 410, and/or the like, for altering the electric current supplied tothe one or more photo transmitters of the plurality of phototransmitters 314. In an example embodiment, the first photo transceiverinterface unit 410 may be configured to increase the electric currentsupplied to each of the one or more photo transmitters. Increase in theelectric current supplied to the one or more photo transmitters causesthe one or more photo transmitters to heat. Because the one or morephoto transmitters are included in the one or more first areas (wherethe moisture has accumulated), the temperature of the one or more firstareas increases. The increase in the temperature of the one or morefirst areas causes the accumulated moisture to evaporate, henceimproving the visibility of the display screen 110.

In an example embodiment, the first photo transceiver interface unit 410may be configured to step-wise increase the electric current supplied tothe one or more photo transmitters. For example, the first phototransceiver interface unit 410 may be first configured to increase theelectric current by a predetermined amount for a predetermined timeperiod. Thereafter, the controller 402 may be configured to repeat thesteps 602-608 to determine whether the moisture has been removed fromthe one or more first areas. If the one or more first areas do not haveaccumulated moisture, the first photo transceiver interface unit 410 maybe configured to reduce the electric current supplied to the one or morephoto transmitters to the default electric current value. However, ifthe controller 402 determines that the one or more first areas still hasthe moisture accumulated, the first photo transceiver interface unit 410may be configured to further increase the electric current supplied tothe one or more photo transmitters by the predetermined amount for apredetermined time period. The aforementioned process of increasing theelectric current is repeated until the electric current supplied to theone or more photo transmitters becomes equal to a threshold electriccurrent value or the moisture is removed from the one or more firstareas.

At step 612, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the pattern generation unit 416, and/orthe like, for generating/updating the moisture accumulation pattern. Inan example embodiment, the moisture accumulation pattern may correspondto a repository that includes at least a list of one or more secondareas on the display screen 110 where the first moisture detection unit412 has historically detected moisture accumulation. Further, themoisture accumulation pattern may include a moisture accumulation countfor each of the one or more second areas. The moisture accumulationcount associated with a second area may correspond a number of times thefirst moisture detection unit 412 has detected moisture accumulation inthe second area. Following table illustrates an example moistureaccumulation pattern:

TABLE 3 An example moisture accumulation pattern. One or more Locationon the Moisture second areas display screen 110 accumulation countsecond area-1 (0, 0)(3, 3)(0, 3)(3, 0) 10 second area-2 (13, 13)(20,20)(13, 20)(20, 13) 7

From the example moisture accumulation pattern, it can be observed thatthe first moisture detection unit 412 has detected 10 instances ofmoisture accumulation in the second area-1. Further, from the exampleaccumulation pattern, it can be observed that the first moisturedetection unit 412 has detected 7 instances of moisture accumulation inthe second area-2.

In an example embodiment, to generate/update the moisture accumulationpattern, the first moisture detection unit 412 may be configured toretrieve the information pertaining to the one or more first areas fromthe first memory device 404. Thereafter, for a first area of the one ormore first areas, the first moisture detection unit 412 may beconfigured to determine whether moisture detection unit 412 haspreviously detected moisture accumulation in the first area from themoisture accumulation pattern. For example, the first moisture detectionunit 412 may be configured to correlate the location of the first areawith the location of the one or more second areas (stored in themoisture accumulation pattern) to determine if the first moisturedetection unit 412 has previously detected moisture accumulation in thefirst area. For example, if the first moisture detection unit 412determines that there exists a second area in the moisture accumulationpattern that has same location as that of the first area, the firstmoisture detection unit 412 may determine that it has previouslydetected moisture accumulation in the first area. Accordingly, the firstmoisture detection unit 412 may update the moisture accumulation countof the second area. On the other hand, if the first moisture detectionunit 412 determines that none of the one or more second areas in themoisture accumulation pattern has the same location as that of the firstarea, the first moisture detection unit 412 may determine that it hasnot previously detected moisture accumulation in the first area.Accordingly, the first moisture detection unit 412 may create a newentry in the moisture accumulation pattern to include the first area asa new second area. Further, the first moisture detection unit 412 mayupdate the moisture accumulation count of the newly added second area as“1”.

In some examples, the scope of the disclosure is not limited to themoisture accumulation pattern only including the list of the one or moresecond areas and the corresponding moisture accumulation. In analternative embodiment, the moisture accumulation pattern may furtherinclude information pertaining to the temperature of the ambientenvironment around the display screen 110 in an instance at the firstmoisture detection unit 412 detects moisture accumulation on the one ormore first areas on the display screen 110. As discussed above, thedisplay screen 110 may include the temperature sensing unit 414 that maybe configured to utilize the temperature sensor (not shown) in thedisplay screen 110 to determine the temperature of the ambientenvironment around the display screen 110. The first moisture detectionunit 412 may be configured to cause the temperature sensing unit 414 todetermine the temperature of the ambient environment in response to thedetection of the one or more first areas. Accordingly, the firstmoisture detection unit 412 may be configured to update/generatemoisture accumulation pattern. Following table illustrates anothermoisture accumulation pattern that includes the information pertainingto the detected temperature of the ambient environment around thedisplay screen 110:

TABLE 4 An example moisture accumulation pattern that includes thetemperature information Temperature One or more Location on the Moistureof ambient second areas display screen 110 accumulation count 0 degreessecond area-1 (0, 0)(3, 3)(0, 3)(3, 0) 10 second area-2 (13, 13)(20,20)(13, 20)(20, 13) 7 −5 degrees second area-1 (0, 0)(3, 3)(0, 3)(3, 0)14 second area-2 (13, 13)(20, 20)(13, 20)(20, 13) 17

The example moisture accumulation pattern illustrated in the table 4depicts that the moisture accumulation count in the second area-1 is 10when the temperature of the ambient environment is 0 degrees, and themoisture accumulation count in the second area-1 is 14 when thetemperature of the ambient environment is −5 degrees. The moistureaccumulation count in the second area-2 is 7 when the temperature of theambient environment is 0 degrees, and the moisture accumulation count inthe second area-2 is 17 when the temperature of the ambient environmentis −5 degrees.

In some example embodiments, the first moisture detection unit 412 maybe configured to utilize the moisture accumulation pattern to predictthe one or more first areas on the display screen 110 where the moisturemay get accumulated. The prediction of the one or more first areas isfurther described in conjunction with FIG. 12.

FIGS. 10A and 10B illustrate example methods 1000 a and 1000 b foroperating the display screen 110 based on the detection of moistureaccumulation on the display screen 110, according to one or moreembodiments described herein.

Referring to the example method 1000 a, the sectional view of thedisplay screen 110 is depicted. The sectional view of the display screen110 includes the glass substrate layer 306 and the photo transceiverlayer 302. In some examples, the glass substrate layer 306 may bedivided into a first measurement area 1002 a, and a second measurementarea 1002 b. Further, it can be observed that the moisture hasaccumulated on the first measurement area 1002 a.

The photo transceiver layer 302 includes the photo transmitters 314a-314 e and the second sensors 316 a-316 e. The photo transmitters 314a, 314 b, and 314 c are positioned below the first measurement area 1002a. Further, the photo transmitters 314 d and 314 e are positioned belowthe second measurement area 1002 b. Similarly, the second sensors 316 a,and 316 b are positioned below the first measurement area 1002 a.Further, the second sensors 316 c, 316 d, and 316 e are positioned belowthe second measurement area 1002 b. When the photo transmitters 314a-314 c generate the light signal, the portion of the light signals(e.g., 1004) get reflected back to the photo transceiver layer 302 dueto presence of the moisture in the first measurement area 1002 a. Theportion of the light signal (e.g., 1004) is detected by the secondsensors 316 a and 316 b. On the other hand, the light signals generatedby the photo transmitters 316 d and 316 e pass through the glasssubstrate layer 306, as moisture has not accumulated in the secondmeasurement area 1002 b. Accordingly, the second sensors 316 c-316 e donot receive the reflected portion of the light signals.

Because the second sensors 316 a-316 b receive the reflected portion ofthe light signal, the second sensors 316 a-316 b generate the secondsignals, which are received by the first photo transceiver interfaceunit 410. Upon reception of the second signals, the first phototransceiver interface unit 410 may be configured to determine theamplitude measurement (i.e., the one or more characteristics) of thesecond signals, as is described in the step 604. In an exampleembodiment, as discussed above, the determined amplitude measurement ofthe second signals corresponds to the measurement of reflectivity of thedisplay screen 110. Thereafter, the first moisture detection unit 412may be configured to compare the determined amplitude measurement of thesecond signal with the first amplitude threshold to determine whetherthe moisture has accumulated in the corresponding measurement area(e.g., measurement area 1002 a), as is described in the step 806. Forexample, the first moisture detection unit 412 may determine whether thedetermined amplitude measurement of the second signals satisfies (e.g.is greater than) the first amplitude threshold based on the comparison.If the determined amplitude measurement satisfies (e.g. is greater than)the first amplitude threshold, the first moisture detection unit 412 maydetermine that the moisture may have got accumulated in the measurementarea 1002 a. Accordingly, the first photo transceiver interface unit 410may increase the electric current supplied to the photo transmitters 314a-314 c associated with the first measurement area 1002 a, as isdescribed in the step 610.

Referring to the example method 1000 b as shown in FIG. 10B, the phototransmitters 314 a-314 e do not generate light signals. In such anembodiment, the second sensors 316 a-316 e may receive the light signalsfrom the ambient environment round the display screen 110. In such anembodiment, the second sensors 316 a-316 b may receive only a portion ofthe light signals from the ambient environment due to presence of themoisture in the first measurement area 1002 a. Therefore, the intensityof the light received by the second sensors 316 a-316 b may be less thanthe intensity of the light signals received by the second sensors 316c-316 e (depicted by dotted light signals 1006). Accordingly, theamplitude of the second signals generated by second sensors 316 a-316 bwill be less than the amplitude of the second signals generated by thesecond sensors 316 c-316 e.

The first photo transceiver interface unit 410 may be configured toreceive the second signals generated by the second sensors 316 a-316 e.Thereafter, the first photo transceiver interface unit 410 may beconfigured to determine the amplitude measurement (measurement of theone or more characteristics) of each of the second signals. The firstmoisture detection unit 412 may be configured to determine whether theamplitude measurement of the second signals satisfies (e.g., less than)the second amplitude threshold. Because the second sensors 316 a-316 bmay receive only the portion of the light signal from the ambientenvironment, the amplitude of the second signals generated by the secondsensors 316 a-316 b may satisfy (e.g., less than) the second amplitudethreshold. Accordingly, the first moisture detection unit 412 may beconfigured to determine that the moisture has accumulated in the firstmeasurement area 1002 a. Thereafter, the first photo transceiverinterface unit 410 may be configured to alter the electric currentsupplied to the photo transmitters 314 a-314 c (associated with thefirst measurement area 1002 a).

FIG. 11 illustrates a flowchart 1100 of a method for operating thedisplay screen 110 based on the detection of the event of thetemperature of the ambient environment around the display screen 110satisfying (e.g., being less than or equal to) the temperaturethreshold, according to one or more embodiments described herein.

At step 1102, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first temperature sensing unit 414,and/or the like, for determining the temperature of the ambientenvironment around the display screen 110. In an example embodiment, thefirst temperature sensing unit 414 may be configured to cause thetemperature sensor in the display screen 110 to determine thetemperature of the ambient environment around the display screen 110.

At step 1104, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first temperature sensing unit 414,and/or the like, for determining whether the determined temperature ofthe ambient environment satisfies (e.g., less than or equal to) thetemperature threshold. In an example embodiment, the temperaturethreshold may correspond to a value of temperature below which there isa high likelihood of moisture accumulation on the display screen 110.For example, if the temperature threshold is 5 degrees Celsius, and ifthe temperature of the ambient environment dips below 5 degrees Celsius,there is a high likelihood of moisture accumulation on the displayscreen 110.

If the first temperature sensing unit 414 determines that the determinedtemperature satisfies (e.g., less than or equal to) the temperaturethreshold, the controller 402 may be configured to perform the step1106. However, if the first temperature sensing unit 414 determines thatthe determined temperature does not satisfy (e.g., greater than) thetemperature threshold, the controller 402 may be configured to repeatthe step 502.

At step 1106, the display screen 110 includes means, such as the controlsystem 310, the controller 402, and/or the like, for detecting theevent. The detected event corresponds to the temperature of the ambientenvironment around the display screen 110 being below the temperaturethreshold. Thereafter, at step 1108, the display screen 110 includesmeans, such as the control system 310, the controller 402, the firstmoisture detection unit 412, and/or the like, for identifying the one ormore first areas from the one or more measurement areas based themoisture accumulation pattern, as is further described in conjunctionwith FIG. 12.

At step 1110, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first photo transceiver interfaceunit 410, and/or the like, for altering the electric current supplied tothe one or more photo transmitters associated with the one or more firstareas using methodologies described above in conjunction with the step610. In some examples, as discussed above, the first photo transceiverinterface unit 410 may be configured to increase the electric currentsupplied to the one or more photo transmitters causing the one or morephoto transmitters to heat. This further leads to heating of the one ormore first areas, which prevents the moisture accumulation in the one ormore first areas. Because the one or more first areas are identifiedbased on the moisture accumulation pattern and accordingly areproactively heated, moisture accumulation on the display screen 110 isproactively prevented.

FIG. 12 illustrates a method for identifying the one or more first areasbased on the moisture accumulation pattern, according to one or moreembodiments described herein.

At step 1202, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first moisture detection unit 412,and/or the like, for determining a moisture accumulation probability foreach of the one or more measurements areas. In an example embodiment,the first moisture detection unit 412 may be configured to determine themoisture accumulation probability based on the moisture accumulationpattern. For example, the first moisture detection unit 412 may beconfigured to determine, for a measurement area of the one or moremeasurement areas, the moisture accumulation count. In some examples, asdiscussed above, the moisture accumulation pattern includes the list ofthe one or more second areas (where the moisture accumulation waspreviously detected) and the corresponding moisture accumulation count.Therefore, the first moisture detection unit 412 may determine themoisture accumulation count for the measurement area from the moistureaccumulation pattern. For example, referring to table 3, the firstmoisture detection unit 412, may be configured to determine that themeasurement area at the location ((0,0)(3,3)(0,3)(3,0)) (i.e., thesecond area-1) on the display screen 110 has the moisture accumulationcount of 10.

Further, the first moisture detection unit 412 may be configured todetermine a total moisture accumulation count from the moistureaccumulation pattern. In an example embodiment, the total moistureaccumulation count may correspond to a total number of times the firstmoisture detection unit 412 has detected moisture accumulation on thedisplay screen 110. For example, referring to table 3, the firstmoisture detection unit 412 determines that total moisture accumulationcount as 17 (i.e., the sum of the moisture accumulation count associatedwith the second area-1 and the moisture accumulation count associatedwith the second area-2). Thereafter, the first moisture detection unit412 may be configured to determine the moisture accumulation probabilityfor the measurement area based on the moisture accumulation countassociated with the measurement area and the total moisture accumulationcount. For instance, the first moisture detection unit 412 may beconfigured to determine the moisture accumulation probability using thefollowing equation:

$\begin{matrix}{{P(m)} = \frac{{Moisture}\mspace{14mu}{accumulation}\mspace{14mu}{count}}{{total}\mspace{14mu}{moisture}\mspace{14mu}{accumulation}\mspace{14mu}{count}}} & (1)\end{matrix}$Where,P(m): moisture accumulation probability associated with the measurementarea m.

To this end, the first moisture detection unit 412 may be configured todetermine the moisture accumulation probability for the measurement areaat the location ((0,0)(3,3)(0,3)(3,0)) as 0.6. Similarly, the firstmoisture detection unit 412 may be configured to determine the moistureaccumulation probability for each of the one or more measurement areas.

At step 1204, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first moisture detection unit 412,and/or the like, for determining, for the one or more measurement areas,whether the respective moisture accumulation probability satisfies (e.g.is greater than or equal to) a first probability threshold. In anexample embodiment, the first probability threshold may correspond to avalue of moisture accumulation probability beyond which there is a highlikelihood of moisture accumulation. In some examples, the firstprobability threshold may be pre-stored in the first memory device 404during manufacturing of the display screen 110.

If the first moisture detection unit 412 determines that the moistureaccumulation probability of a measurement area of the one or moremeasurement areas satisfies (e.g. is greater than) the first probabilitythreshold, the first moisture detection unit 412 may be configured toperform the step 1206. At step 1206, the display screen 110 includesmeans, such as the control system 310, the controller 402, the firstmoisture detection unit 412, and/or the like, for classifying themeasurement area as the first area. Thereafter, the controller 402 maybe configured to perform the step 1110.

However, if the first moisture detection unit 412 determines that themoisture accumulation probability of the measurement area does notsatisfy (e.g., less than) the first probability threshold, the firstmoisture detection unit 412 may be configured to repeat the step 1204for remaining measurement areas of the one or more measurement areas.

In an example embodiment, based on the method described in the flowchart1200, the first moisture detection unit 412 identifies the one or morefirst areas from the one or more measurement areas that have a highmoisture accumulation probability in comparison to other measurementareas in the one or more measurement areas. After the identification ofthe one or more first areas, the controller 402 may be configured toperform the step 1108.

In some embodiments, the scope of the disclosure is not limited to theidentifying the one or more first areas based on only on the moistureaccumulation pattern, as is illustrated in table 3. In an alternativeembodiment, the first moisture detection unit 412 may be configured toidentify the one or more first areas based on the moisture accumulationpattern and the temperature of the ambient environment around thedisplay screen 110. In such an embodiment, the first moisture detectionunit 412 may utilize the moisture accumulation pattern that includes thetemperature data along with the moisture accumulation count associatedwith the one or more second areas (i.e., the measurement areas where themoisture accumulation was previously detected by the first moisturedetection unit 412). For example, the first moisture detection unit 412may be configured to utilize the moisture accumulation patternillustrated in table 4 for identification of the one or more firstareas. One such method of identification of the one or more first areasis described in conjunction with FIG. 13.

FIG. 13 illustrates a flowchart 1300 of another method for identifyingthe one or more first areas based on the moisture accumulation pattern,according to one or more embodiments described herein.

At step 1302, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first temperature sensing unit 414,and/or the like, for determining the current temperature of the ambientenvironment around the display screen 110. In an example embodiment, thefirst temperature sensing unit 414 may be configured to utilize similarmethodologies as described in the step 1102 to determine the currenttemperature of the ambient environment around the display screen 110.

At step 1304, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first moisture detection unit 412,and/or the like, for retrieving a list of second areas from the moistureaccumulation pattern based on the determined current temperature. In anexample embodiment, the list of second areas may correspond to themeasurement areas on the display screen 110 where the moistureaccumulation was previously detected at the determined currenttemperature. For example, if the current temperature is −5 degreesCelsius, the first moisture detection unit 412 may determine thatpreviously the moisture accumulation was detected in the second area-1and the second area-2 (referring to table 4). Further, the firstmoisture detection unit 412 may be configured to retrieve the moistureaccumulation count associated with the second areas in the retrievedlist of second areas. For example, the first moisture detection unit 412determines that the second area-1 has moisture accumulation count of 14at −5 degrees' Celsius temperature. Similarly, the first moisturedetection unit 412 may retrieve the moisture accumulation count of thesecond area-2 from the moisture accumulation pattern (referring to table4).

Thereafter, the first moisture detection unit 412 may be configured torepeat the steps 1202, 1204, and 1206 to identify the one or more firstareas. For example, the first moisture detection unit 412 may determinethe moisture accumulation probability for each of the one or moremeasurement areas in the display screen 110 based on the moistureaccumulation count included in the list of second areas and the totalmoisture accumulation count determined from the list of second areas.For example, the first moisture detection unit 412 determines, from thelist of second areas, that the moisture accumulation count of themeasurement area at the location ((0,0)(3,3)(0,3)(3,0)) is 14 when thetemperature of the ambient environment around the display screen 110 is−5 degrees' Celsius. Further, the first moisture detection unit 412determines that the total moisture accumulation count is 31 when thetemperature of the ambient environment is −5 degrees Celsius.Thereafter, based on the moisture accumulation count and the determinedtotal moisture accumulation count, the first moisture detection unit 412may be configured to determine the moisture accumulation probability foreach of the one or more measurement areas.

Further, the first moisture detection unit 412 may be configured todetermine, for the measurement area of the one or more measurementareas, whether the determined moisture accumulation probabilitysatisfies (e.g., greater than) the first probability threshold. If thefirst moisture detection unit 412 determines that the moistureaccumulation probability associated with the measurement area satisfies(e.g., greater than) the first probability threshold, the first moisturedetection unit 412 may classify the measurement area as the first area.

In some example embodiments, the scope of the disclosure is not limitedto identifying the one or more first areas based on automatic detectionof moisture accumulation on the display screen 110 (based either on themoisture accumulation pattern or based on thetransmissivity/reflectivity of the displays screen 110). In analternative embodiment, the operator 108 may provide a touch input onthe displays screen 110 to indicate the first area where the moisturemay have got accumulated. One such method of identification of the firstarea based on the reception of the touch input is described inconjunction with FIG. 14.

FIG. 14 illustrates a flowchart 1400 of a method for operating thedisplay screen 110 based on detection of the event (for example, areception of touch input), according to one or more embodimentsdescribed herein.

At step 1402, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first touch interface unit 408,and/or the like, for receiving the first signals from a set of firstsensors of the plurality of first sensors. In an example embodiment, thereception of the first signals may be indicative of the reception of thetouch input from the operator 108 on the display screen 110. Further,the first touch interface unit 408 receives the first signals from theset of first sensors and detects the event as the reception of the touchinput.

At step 1404, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first touch interface unit 408,and/or the like, for determining the location of the set of firstsensors on the display screen 110. As discussed above, the first memorydevice 404 includes data pertaining to the plurality of first sensors.The data includes the location information of the plurality of firstsensors and the unique address associated with each first sensor of theplurality of first sensors. In an example embodiment, based on thereception of the first signals, the first touch interface unit 408 maybe configured to uniquely identify the set of first sensors of theplurality of first sensors 318 that has received the touch input.Thereafter, the first touch interface unit 408 may be configured todetermine the location of the set of first sensors 318 on the displayscreen 110 from the data pertaining to the plurality of first sensors318 stored in the first memory device 404.

At step 1406, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first touch interface unit 408,and/or the like, for identifying the one or more areas on the displayscreen 110 based on the determined location of the set of first sensors.As discussed, because the first memory device 404 includes theinformation pertaining to the unique address and the location of each ofthe plurality of first sensors 318, the first touch interface unit 408determines the location of the set of first sensors from the firstmemory device 404. Based on the location of the set of first sensors,the first touch interface unit 408 may be configured to identify the oneor more areas. In some examples, the first photo transceiver interfaceunit 410 may be configured to consider the one or more identified areasas the one or more first areas. The identification of the one or morefirst areas is further described in FIG. 16.

In some examples, the scope of the disclosure is not limited to identifythe one or more areas as the areas on the display screen 110 that havereceived the touch input. In an alternative embodiment, the first touchinterface unit 408 may be configured to identify the one or more areasbased on a gesture input received from the operator 108. In an exampleembodiment, the gesture may correspond to an action performed by theoperator 108 that involves one or more set of first sensors receivingthe touch input from the operator 108 in a predetermined sequence. Forexample, the operator 108 provides a gesture, which causes a first setof first sensors to generate the first signals followed by a second setof first sensors to generate the first signals. In such embodiment, thefirst touch interface unit 408 may be configured to first receive thefirst signals from the first set of first sensors followed by the firstsignal from the second set of first sensors. In some examples, the firstset of first sensors is located adjacent to the second set of firstsensors. Further, the first touch interface unit 408 may be configuredto identify the area as the location of the one or more set of firstsensors. For example, the first touch interface unit 408 may beconfigured to identify the area as the location of the first set offirst sensors and the second set of first sensors.

In yet another alternative embodiment, the first touch interface unit408 may be configured to identify the area as the location of the one ormore sets of first sensors and an area encompassed by the one or moreone or more sets of first sensors, based on the gesture performed by theoperator 108. For example, if the operator 108 provides touch input todraw a closed loop on the display screen 110, the first touch interfaceunit 408, in such an embodiment, may be configured to identify the areathat at least includes the area encompassed by the closed loop.

At step 1408, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first photo transceiver interfaceunit 410, and/or the like, for altering the electric current supplied tothe one or more photo transmitters associated with the one or more firstareas (identified in the step 1404). In an example embodiment, the firstphoto transceiver interface unit 410 may be configured to utilizesimilar methodologies as described in the step 610 to alter the electriccurrent supplied to the one or more photo transmitters.

At step 1410, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first touch interface unit 408,and/or the like, for generating/updating a display screen usage pattern.In an example embodiment, the display screen usage pattern may includeinformation pertaining to one or more third areas on the display screen110 which has historically received the touch input from the operator108. In an example embodiment, the display screen usage pattern mayfurther include location information pertaining to the one or more thirdareas and a touch input count associated with each of the one or morethird areas. In an example embodiment, the touch input count maycorrespond to a number of times that a third area of the one or morethird areas have received the touch input from the operator 108.Following table illustrates an example display screen usage pattern:

TABLE 5 Display screen usage pattern One or more Location on the Touchthird areas display screen 110 input count Third area-1 (0, 0)(3, 3)(0,3)(3, 0) 10 Third area-2 (13, 13)(20, 20)(13, 20)(20, 13) 7

From the aforementioned table, it can be observed that the third area-1at the location ((0,0)(3,3)(0,3)(3,0)) has historically received 10touch inputs. Similarly, the third area-2 at the location((13,13)(20,20)(13,20)(20,13)) has historically received 7 touch inputs.

To update/generate the display screen usage pattern, the first touchinterface unit 408 may determine whether the identified area (identifiedin the step 1404), which has received the touch input, is included inthe display screen usage pattern. In an example embodiment, the firsttouch interface unit 408 may be configured to compare the location ofthe identified area with the location of the one or more third areasincluded in the display screen usage pattern to determine whether theidentified area, which has received the touch input, is included in thedisplay screen usage pattern. For example, the first touch interfaceunit 408 determined that the area, which has received the touch input,has a location ((0,0)(3,3)(0,3)(3,0)). Further, based on the comparisonof the location of the identified area and the location of the one ormore third areas, the first touch interface unit 408 determines that theidentified area is included in the display screen usage pattern as thethird area-1. Thereafter, the first touch interface unit 408 may beconfigured to update the touch input count of the third area-1 to 11.

On the other hand, if, based on the comparison of the location of theidentified area and the locations of the one or more third areas, thetouch interface unit 408 determines that the identified area is notpresent in the display screen usage pattern, the first touch interfaceunit 408 may be configured to update the display screen usage pattern toinclude the identified area as a new third area. Further, the touchinterface unit 408 may be configured to update the touch input count ofthe new third area to 1.

In some examples, the moisture detection unit 412 of the display screen110 may be configured to utilize the display screen usage pattern toidentify a set of third areas from the one or more third areas which mayregularly receive touch input from the operator 108. Because the set ofthird areas may regularly receive the touch input, the controller 402may instruct the first photo transceiver interface unit 410 toproactively heat the set of third areas so that moisture does not getaccumulated in the set of third areas. The prediction of the set ofthird areas is further described in conjunction with FIG. 17.

In some example embodiments, the scope of the disclosure is not limitedto altering the electric current supplied to the one or more phototransmitters every time the touch input is received on the displayscreen 110. Additionally or alternatively, the method described in theflowchart 1400 may be performed based on the current temperature of theambient environment around the display screen 110. Such animplementation is described in conjunction with FIG. 15.

FIG. 15 illustrates a flowchart 1500 of another method for operating thedisplay screen 110 based on detection of the event of reception of thetouch input on the display screen 110 while the temperature of theambient environment satisfies (e.g. is less than) the temperaturethreshold, according to one or more embodiments described herein.

At step 1502, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first temperature sensing unit 414,and/or the like, for determining the current temperature of the ambientenvironment around the display screen 110. In an example embodiment, thefirst temperature sensing unit 414 may be configured to determine thetemperature of the ambient environment using the similar methodologiesas described in the step 1102.

At step 1504, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first temperature sensing unit 414,and/or the like, for determining whether the determined currenttemperature satisfies (e.g. is less than) the temperature threshold. Ifthe first temperature sensing unit 414 determines that the determinedcurrent temperature satisfies (e.g., less than) the temperaturethreshold, the controller 402 may be configured to perform step 1402 ofFIG. 14. However, if the first temperature sensing unit 414 determinesthat the current temperature of the ambient environment around thedisplay screen 110 does not satisfies (e.g., greater than) thetemperature threshold, the first temperature sensing unit 414 may beconfigured to repeat the step 502 in FIG. 5.

As discussed above in the flowchart 1400, the controller 402 mayinstruct the first photo transceiver interface unit 410 to heat the oneor more first areas (i.e., the one or more areas that have received thetouch input from the operator 108) to avoid moisture accumulation in theone or more first areas.

FIG. 16 illustrates an example method 1600 for identifying the one ormore first areas, according to one or more embodiments described herein.

The example method 1600 illustrates that the display screen 110 includesthe plurality of first sensors 318. Further, the example method depictsthat the set of first sensors 1602 of the plurality of first sensors 318has generated the first signals (depicted by the 1604). The generatedfirst signals are transmitted to the first touch interface unit 408. Onreceiving the first signals, the first touch interface unit 408 maygenerate a list of first sensors (e.g., table 1606) that includes thelocation of each first sensor in the set of first sensors from which thefirst touch interface unit 408 has received the first signals. In someexamples, the list of the first sensors includes the locationinformation of each first sensor in the set of first sensors. Forexample, from the table 1606, it can be observed that the list of firstsensors includes first sensors located at the coordinates (3,3), (0,3),(0,0), and (2,2). Thereafter, the first touch interface unit 408 may beconfigured to utilize techniques such as, Cartesian coordinates system,to determine periphery of an area 1608. The periphery of the area isdefined in such a manner that the area 1608 includes the first sensorsin the list of first sensors (e.g., table 1606).

After the identification of the area 1608 (which has received the touchinput), the moisture detection unit 412 may be configured to considerthe identified area as the first area. Accordingly, the phototransceiver interface unit 410 alters the electric current supplied tothe one or more photo transmitters included in the first area to heatthe first area. Heating the first area avoid moisture accumulation inthe first area.

FIG. 17 illustrates a flowchart 1700 of another method of operating thedisplay screen 110 based on the detection of the event of thetemperature of the ambient environment satisfying (e.g., less than) thethreshold temperature, according to one or more embodiments describedherein.

At step 1702, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first temperature sensing unit 414,and/or the like, for determining the current temperature of the ambientenvironment around the display screen 110. In an example embodiment, thefirst temperature sensing unit 414 may be configured to determine thetemperature of the ambient environment using the similar methodologiesas is described in the step 1102.

At step 1704, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first temperature sensing unit 414,and/or the like, for determining whether the determined currenttemperature satisfies (e.g. is less than) the temperature threshold. Ifthe first temperature sensing unit 414 determines that the determinedcurrent temperature satisfies (e.g., less than) the temperaturethreshold, the controller 402 may be configured to perform the step1706. However, if the first temperature sensing unit 414 determines thatthe current temperature of the ambient environment around the displayscreen 110 is does not satisfy (e.g., greater than) the temperaturethreshold, the first temperature sensing unit 414 may be configured torepeat the step 502.

At step 1706, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first touch interface unit 408,and/or the like, for identifying a set of third areas from the one ormore third areas that may have high probability of receiving the touchinput from the operator 108. In an example embodiment, the first touchinterface unit 408 may be configured to utilize the display screen usagepattern to identify the set of third areas. The identification of theset of third areas is described later in conjunction with FIG. 18.

In some examples, after the identification of the set of third areas,the first photo transceiver interface unit 410 may be configured toidentify the set of third areas as the one or more first areas.Thereafter, at step 1708, the display screen 110 includes means, such asthe control system 310, the controller 402, the first photo transceiverinterface unit 410, and/or the like, for altering the electric currentsupplied to the one or more photo transmitters using the methodologiesas is described above in the step 610. In an example embodiment, thefirst photo transceiver interface unit 410 may increase the electriccurrent supplied to the one or more photo transmitters associated withthe one or more first areas causing the one or more photo transmittersto heat, which prevents accumulation of the moisture in the one or morefirst areas of the display screen 110.

FIG. 18 illustrates a flowchart 1800 of a method for identifying the setof third area from the one or more third areas on the display screen110, according to one or more embodiments described herein.

At step 1802, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first touch interface unit 408,and/or the like, for retrieving the display screen usage pattern fromthe first memory device 404. As discussed, the display screen usagepattern includes information pertaining to the one or more third areasthat have historically received the touch input from the operator 108.Further, as discussed, the information in the display screen usagepattern further includes the touch input count associated with each ofthe one or more third areas.

At step 1804, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first touch interface unit 408,and/or the like, for determining a touch input reception probability foreach of the one or more third areas. In an example embodiment, the touchinput reception probability may correspond to a likelihood of a thirdarea of the one or more third areas receiving the touch input. In anexample embodiment, the first touch interface unit 408 may be configuredto determine the touch input reception probability for each of the oneor more third areas based on the touch input count and the total touchinput count. For example, referring to table 5, the first touchinterface unit 408, may be configured to determine that the third area-1has the touch input count of 10. Further, the first touch interface unit408 may determine, from table 5, that total touch input count is 17.

Thereafter, the first touch interface unit 408 may be configured todetermine the touch input reception probability for a third area of theone or more third areas based on the touch input count associated withthe third area and the total touch input count. For instance, the touchinterface unit 408 may be configured to determine the touch inputreception probability using the following equation:

$\begin{matrix}{{P(m)} = \frac{{touch}\mspace{14mu}{input}\mspace{14mu}{count}}{{total}\mspace{14mu}{touch}\mspace{14mu}{input}\mspace{14mu}{count}}} & (1)\end{matrix}$Where,P(m): Touch input reception probability of m^(th) third area.

For example, the first touch interface unit 408 may be configured todetermine the touch input reception probability for the third area-1 as0.6. Similarly, the first touch interface unit 408 may be configured todetermine the touch input reception probability for each of the one ormore third areas.

At step 1806, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first touch interface unit 408,and/or the like, for determining, for the third area of the one or morethird areas, whether the respective touch input reception probabilitysatisfies (e.g. is greater than or equal to) a second probabilitythreshold. If the first touch interface unit 408 determines that thetouch input reception probability of the third area of the one or morethird areas satisfies (e.g., greater than) the second probabilitythreshold, the first touch interface unit 408 may be configured toperform the step 1808. At step 1808, the display screen 110 includesmeans, such as the control system 310, the controller 402, the firsttouch interface unit 408, and/or the like, for classifying the thirdarea as the set of third areas. Thereafter, the first touch interfaceunit 408 may be configured to repeat the step 1806 for remaining thirdareas of the one or more third areas. However, if the first touchinterface unit 408 determines that the touch input reception probabilityof the third area does not satisfy (e.g., less than) the secondprobability threshold, the first touch interface unit 408 may beconfigured to repeat the step 1806 for remaining third areas of the oneor more third areas.

In an example embodiment, based on the method described in the flowchart1800, the first touch interface unit 408 identifies the set of thirdareas from the one or more third areas that have a high touch inputreception probability in comparison to other third areas in the one ormore third areas. After the identification of the set of third areas,the controller 402 may be configured to perform the step 1708.

In some embodiments, the scope of the disclosure is not limited toidentifying the one or more first areas either based on the touch inputreception probability (i.e., flowchart 1700 and flowchart 1800)associated with the one or more third areas on the display screen 110 orbased on the determination of the moisture accumulation probability(i.e., the flowchart 1100 and the flowchart 1200) associated with theone or more measurement areas. In an alternative embodiment, the firstmoisture detection unit 412 may be configured to identify the one ormore first areas based on both the touch input reception probabilityassociated with the one or more third areas and the moistureaccumulation probability associated with the one or more measurementareas. One such method of identification of the one or more first areasis described in conjunction with FIG. 19.

FIG. 19 illustrates a flowchart 1900 of another method for identifyingthe one or more first areas, according to one or more embodimentsdescribed herein.

At step 1902, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first moisture detection unit 412,and/or the like, for determining the moisture accumulation probabilityfor each of the one or more measurement areas. In an example embodiment,the first moisture detection unit 412 may be configured to determine themoisture accumulation probability based on the methodologies describedin the flowchart 1200. At step 1904, the display screen 110 includesmeans, such as the control system 310, the controller 402, the firsttouch interface unit 408, and/or the like, for determining the touchinput reception probability for each of the one or more third areasbased on the methodologies described in the flowchart 1800.

In some examples, the one or more measurement areas on the displayscreen 110 may include the one or more third areas (which has receivedthe touch input from the operator 108). As discussed above, the displayscreen 110 includes the one or more measurement areas throughout thespan of the display screen 110. Further, as discussed above, theoperator 108 may have provided touch inputs on the one or more thirdareas on the display screen 110. Therefore, a first set of measurementareas of the one or more measurement areas may be included in the one ormore third areas. In some examples, the operator 108 may have notprovided touch input on certain portion of the display screen 110.Therefore, a second set of measurement areas of the one or moremeasurement areas may not be included in the one or more third areas.

Because the first set of measurement areas has received the touch inputsfrom the operator 108, the first set of measurement areas may have boththe touch reception probability and the moisture accumulationprobability associated with them. The following table illustrates themoisture accumulation probability and the touch reception probabilityassociated with each of the one or more measurement areas:

TABLE 6 The moisture accumulation probability and the touch receptionprobability associated with each of the one or more measurement areas.Moisture Touch input accumulation Measurement area reception probabilityprobability Measurement area-1 0.3 0.5 Measurement area-4 0 0.3Measurement area-3 0.7 0.2

From table 6, it can be observed that the measurement area-1 andmeasurement area-3 has both the touch input reception probability andthe moisture accumulation probability associated with them. Therefore,the measurement area-1 and measurement area-2 are part of the first setof measurement areas. On the other hand, the measurement area-2 only hasthe moisture accumulation probability associated with it. Therefore, themeasurement area-2 is part of the second set of measurement areas.

At step 1906, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first moisture detection unit 412,and/or the like, for determining a score for each of the one or moremeasurement areas based on the touch input reception probability and themoisture accumulation probability associated with each of the one ormore measurement areas. In an example embodiment, the score associatedwith a measurement area may correspond to a weighted sum of the touchinput reception probability and the moisture accumulation probabilityassociated with the measurement area. The first moisture detection unit412 may be configured to utilize following equation to determine theweighted sum:Score=w _(m)×moisture accumulation probability+w _(t)×touch inputreception probability   (2)Where,w_(m): weight associated with the moisture accumulation probability; andw_(t): weight associated with the touch input reception probability.

In an example embodiment, the weight associated with the moistureaccumulation probability (hereinafter referred to as the first weight)may correspond to a measurement of importance assigned to the moistureaccumulation probability in comparison to the importance of the touchinput reception probability. In an example embodiment, the weightassociated with the touch input reception probability (hereinafterreferred to as second weight) may correspond to a measurement ofimportance assigned to the touch input reception probability incomparison to the moisture accumulation probability. In an exampleembodiment, the first weight and the second weight may be pre-stored inthe first memory device 404 during manufacturing of the display screen110. In an alternative embodiment, the operator 108 of the displayscreen 110 may provide input corresponding to the value of the firstweight and the second weight during initialization of the display screen110, without departing from the scope of the disclosure.

For example, if the first weight is 0.7 and the second weight is 0.3,more importance is assigned to moisture accumulation probability incomparison to the touch input reception probability. To this end, themoisture detection unit 412 may determine the score for the measurementarea-1 as 0.44. Similarly, the moisture detection unit 412 may determinethe score for the measurement area-2 and measurement area-3 as 0.49 and0.35, respectively.

After determining the score for each of the one or more measurementareas, at step 1908, the display screen 110 includes means, such as thecontrol system 310, the controller 402, the first moisture detectionunit 412, and/or the like, for determining whether the score associatedwith a measurement area satisfies (e.g., greater than) a scorethreshold. If the first moisture detection unit 412 determines that thescore associated with the measurement area satisfies (e.g., greaterthan) the score threshold, the first moisture detection unit 412 may beconfigured to perform the step 1910. At step 1910, the display screen110 includes means, such as the control system 310, the controller 402,the first moisture detection unit 412, and/or the like, for classifyingthe measurement area as the first area. Thereafter, the step 1908 isrepeated for other measurement areas in the one or more measurementareas.

However, if at the step 1908, the first moisture detection unit 412determines that the score associated with the measurement area does notsatisfy (e.g., less than) the score threshold, the first moisturedetection unit 412 may be configured to repeat the step 1908 for othermeasurement areas in the one or more measurement areas.

FIG. 20 illustrates a flowchart 2000 of another method for operating thedisplay screen 110 based on the detection of the event of display of thepredetermined content on the display screen 110, according to one ormore embodiments described herein.

At step 2002, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first photo transceiver interfaceunit 410, and/or the like, for determining whether the predeterminedcontent is being displayed on the display screen 110. In someembodiments, because the controller 402 controls the display of contenton the display screen 110 (based on the electric current supplied to theplurality of photo transmitters), the controller 402 can determine whatcontent is being displayed through which photo transmitter of theplurality of photo transmitters 314. Accordingly, the controller 402 maydetermine whether the content displayed on the display screen 110includes the predetermined content.

If the controller 402 determines that the predetermined content is beingdisplayed on the display screen 110, the controller 402 may beconfigured to perform step 504. However, if the controller 402determines that the predetermined content is not being displayed on thedisplay screen 110, the controller 402 may be configured to repeat thestep 502.

At step 2004, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first photo transceiver interfaceunit 410, and/or the like, for determining the location on the displayscreen 110 where the predetermined content is being displayed on thedisplay screen 110. As discussed, because the controller 402 controlsthe display of the content on the display screen 110, controller 402 candetermine the one or more photo transmitters of the plurality of phototransmitters 314 that are displaying the predetermined content (e.g.,based on the unique address associated with each of the plurality ofphoto transmitters). Further, based on the unique address associatedwith the one or more photo transmitters, the controller 402 may beconfigured to determine the location of the one or more phototransmitters on the display screen 110. For example, the controller 402may be configured to utilize the location information, pertaining to theplurality of photo transmitters 314, stored in the first memory device404 to determine the location of the one or more photo transmitters.

After determining the location of the one or more photo transmitters, inan example embodiment, the first moisture detection unit 412 may beconfigured to determine the location of the one or more phototransmitters as the first area.

At step 2006, the display screen 110 includes means, such as the controlsystem 310, the controller 402, the first photo transceiver interfaceunit 410, and/or the like, for altering the electric current supplied tothe one or more photo transmitters causing the one or more phototransmitters to heat. Heating of the one or more photo transmitters maycause the first area to heat, which avoids moisture accumulation in thefirst area.

In some example embodiments, the scope of the disclosure is not limitedto the predetermined content being displayed at the fixed location onthe display screen 110. In an alternative embodiment, the operator 108may be configured to provide input such as, but not limited to, thetouch input to modify the location of the predetermined content on thedisplay screen 110. The controller 402 may be configured to determineupdated location of the predetermined content on the display screen 110and accordingly update the first area. Thereafter, the first phototransceiver interface unit 410 may alter the electric current suppliedto the one or more photo transmitters associated with the updated firstarea causing the updated first area to heat.

Such embodiment allows the operator 108 to modify the heating region bysimply providing input (e.g., touch input) to modify the location of thepredetermined content on the display screen 110.

FIG. 21 illustrates an example method 2100 of identifying the first areabased on display of the predetermined content on the display screen 110,according to one or more embodiments described herein.

The example method 2100 illustrates the display screen 110 displayingthe content 2102. Further, the content 2102 includes a floating icon2104, which corresponds to the predetermined content. As discussed, thefirst photo transceiver interface unit 410 may be configured to alterthe electric current supplied to the one or more photo transmittersdisplaying the predetermined content on the display screen 110. Thiscauses the first area where the floating icon is being displayed to heatand accordingly avoid moisture accumulation in the first area.

For example, the operator 108 observes that moisture has accumulated inthe portion 2106 of the display screen 110 (e.g., depicted by 2105). Insuch embodiment, the operator 108 may provide touch input on the displayscreen 110 to move the floating icon 2104 to the portion 2106 (depictedby 2108). The controller 402 of the display screen 110 may receive thetouch input corresponding to the change in the location of the floatingicon 2104. In response to the reception of the touch input correspondingto the change in location of the floating icon 2104, the controller 402may be configured to instruct the one or more photo transmitters at theupdated location (i.e., the portion 2106) of the display screen 110 todisplay the floating icon 2104. Further, the first photo transceiverinterface unit 410 may be configured to alter the electric currentsupplied to the one or more photo transmitters at the updated location(i.e., the portion 2106), causing the portion 2106 on the display screen110 to heat. In some examples, heating of the portion 2106 may cause theremoving of the accumulated moisture.
